I agree, very fast growing conifer. 😀 Mine grew twice its size in one year but I'm keeping in a pot so it slows down the growth a bit. I also prune the roots every other year to slow it down as I kind of like it among my perennial beds.
Oh yeah, I can't stand builders and the mess they leave behind in the garden! I had a boiler replaced this winter and I'm still finding bits of drainage pipes and nails left behind in the back garden. Why can't they clean after themselves when they're done. 😈
